Genetics Review

Front

What is a Punnett Square?

Back

A Punnett Square is a diagram used to predict the genotypes of a particular cross or breeding experiment. It shows the possible combinations of alleles from the parents.

Who is known as the Father of Genetics?

Back

Gregor Mendel is known as the Father of Genetics for his work on inheritance patterns in pea plants.

What controls genetic traits?

Back

Genes control genetic traits. They are segments of DNA that determine specific characteristics.

Front

What is a genotype?

Back

A genotype is the genetic makeup of an organism, represented by the alleles it possesses.

Front

What is a homozygous dominant genotype?

Back

A homozygous dominant genotype has two identical dominant alleles (e.g., BB).

Front

What is a heterozygous genotype?

Back

A heterozygous genotype has one dominant and one recessive allele (e.g., Bb).

Front

What is the difference between phenotype and genotype?

Back

Phenotype is the observable physical characteristics of an organism, while genotype is the genetic makeup that determines those traits.

Front

What is the purpose of a pedigree chart?

Back

A pedigree chart is used to track the inheritance of traits through generations in a family.

Front

What is the law of segregation?

Back

The law of segregation states that during the formation of gametes, the two alleles for a trait separate from each other.

Front

What is the law of independent assortment?

Back

The law of independent assortment states that alleles for different traits are distributed to gametes independently of one another.
